The system has a number of key components that you will
need to be familiar with before attempting to use it:
• Residual Current Device (RCD) and Miniature Circuit
Breakers (MCB): The RCD is provided to protect the
user from a potentially lethal electric shock. It will turn o
(trip) if a fault occurs on the system. To ensure the RCD
is working correctly, the test button should be operated
each time the vehicle is connected to the mains supply.
The MCBs operate in a similar way to traditional fuses
and are provided to protect the wiring from an overload
or short circuit. If an overload occurs, the MCB will switch
o the supply. If this occurs, the cause of the fault should
be investigated before switching the MCB back on.
• 12V DC Fuses: These fuses are provided to protect the
various 12V circuits from an overload or short circuit.
If a fuse does blow, the cause of the fault should be
investigated before a replacement. When replacing a
fuse, always replace with a fuse of the correct value, never
replace with a higher value as this could damage the
wiring harness.
• Charger Switch: The charger switch turns on the internal
battery charger that will charge the batteries and provide
12V power to the interior of the vehicle. The switch will
illuminate when the unit is plugged into the mains supply
and the switch is pushed to the ‘IN’ position.
• Heater Switch: The heater switch turns on the 230V
supply to the water and heating system. The switch will
illuminate when the unit is plugged into the mains supply
and the switch is pushed to the ‘IN’ position.
• Shutdown Button: The shutdown button should be used
when the vehicle is in storage or not being used for a long
period of time. This allows the leisure electronics to be
turned o when not required to save battery power.
• Operation while driving: The EC176 system is designed to
shutdown parts of the system whilst the vehicle engine is
running. This is to meet Electro Magnetic Compatibility
(EMC) regulations and to ensure the safe operation of
the system. Please ensure the system shutdown switch
on the PSU is in the 'ON' (button in) position before
driving. This will ensure the electronic system is active and
will therefore be able to control the charging process,
supply the refrigerator and monitor other system circuits
Please note: Apart from the changing of fuses and the testing
and resetting of the RCD and MCBs, no maintenance is
required on the PSU unit. If a problem develops with your
unit, please contact your supplying dealer or a qualified
electrician.
